In fact, Shen Tunan's gunshot wound was caused by himself. He tried his best to recover the custody rights of the customs, but with little success. When he rushed to the bank, he was chased and he had no choice but to shoot and wound himself.

He knew that Kang Shaojie had a long private room in the Licha Hotel. He booked a room in the Licha Hotel in advance and hung a red flag in it. Then he reported to Kang Shaojie. Kang Shaojie sent Lin Qiaosong to take people to stay in that room. Shen Tunan hid directly in the room.In that room, the killers Zhang Mingquan was looking for arrived soon after. Lin Qiaosong mistakenly thought they were enemies and shot at them wildly. The killers suffered all casualties. Lin Qiaosong took the only survivor back for interrogation.

In desperation, Shen Tunan used bitter tactics to win the support of most people. Huang Congyun persuaded him not to gamble with his life anymore. Shen Tunan asked him to hide the matter from Wei Ruolai. He felt that it was not safe and wanted to take back the customs custody rights as soon as possible., it was best to let Chiang Kai-shek personally come forward to finalize the matter. At this time, Shen Tunan asked Huang Congyun to find a way to make the matter bigger. Huang Congyun immediately contacted “Nanjing Daily” to report the murder of Shen Tunan.
